-How good were the teams BYU played.
-How many games did BYU win.

You can't really do this in advance. Yes, its fun to speculate, but trying to rationalize final opinion based on speculative hopes seems dumb to me.

So far, in hindsight, it looks like BYU beat one pretty good team, 4 "meh" teams and lost to one not very good team.

The loss to that team makes the result so far disappointing. Yes, of course it could be worse.
